Fastio – Fasting Tracker

Time your fasting window

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Pick your protocol, tap start, and Fastio tracks every hour of your fasting and eating window — with streaks and history to keep you consistent. Intermittent fasting works best when you actually know where you are in the window. Fastio is the clean, no-fuss timer that tracks your fast from the first hour to the last — so you can just follow your plan. Pick a protocol like 16:8, 18:6 or 20:4, tap to start, and Fastio counts your fasting and eating windows for you. See your current stage at a glance, keep a streak of completed fasts, and look back over a history that shows how consistent you've really been. WHY FASTIO • Always know your window. A clear timer shows exactly how long you've fasted and what's left. • Popular protocols, ready to go. 16:8, 18:6, 20:4, OMAD or set your own hours. • Build a streak. Completed fasts add up into a record that keeps you consistent. • Simple and calm. No noise, no clutter — just your fast and your progress. WHAT YOU GET • A fasting timer with start, end and elapsed stages • Preset protocols plus fully custom windows • Streaks and a full history of your fasts • Daily and weekly consistency at a glance • Optional reminders to start and end your window • Notes to log how each fast felt Fastio is a timing and tracking tool, not medical advice. Talk to a doctor before changing how you eat, especially if you have a health condition, are pregnant or take medication. FREE AND PREMIUM Fastio is free to time your fasts.
